| 1 | The bulk transfer coefficients and surface fluxes on the western Tibetan Plateau显示文摘On the gradient observational data of the atmospheric surface layer from September 1997 to December 1998 collected by two sets of Automatic Weather Station (AWS) installed in Gaize and Shiquanhe on the western Tibetan Plateau, mean surface roughness lengths at the two stations above are determined to be 2.7 and 2.9 cm, respectively. The bulk transfer coefficients each day are computed by the profile-flux method, means of the bulk transfer coefficient for momentum (i.e. drag coefficient) in 1998 are 4.83×10-3 and 4.75×103 at the two stations. The surface fluxes of momentum, sensible heat and latent heat each day are further estimated by the bulk formulas, annual mean of these fluxes is 3.4×10-2 and 1.8×102N/m2, 73.1 and 67.2 W/m2, 15.4 and 2.9 W/m2, respectively. The diurnal and seasonal variations are obtained by a composite method and the relationships among the heat transfers between land and atmosphere, plateau monsoon and plateau rain season are also discussed. | Guoping Li Tingyang Duan Yuanfa Gong | 2000 | Chinese Science Bulletin2000，45，13： | 13 |

| 3 | Knowledge,Attitude and Practice(K-A-P)of Cancer Nutrition in Chinese Medical Staff显示文摘Objective The present study was designed to investigate knowledge,attitude,and practice(K-A-P)toward cancer nutrition among medical staff in China,and to provide a basis for nutritional oncology training in clinical oncology practice in China in order to improve clinical treatment outcomes.Method This was a multicenter,cross-sectional study involving 3036 clinicians selected from 138 hospitals in 13 provinces across China.KAP scores were collected via questionnaires.Results The overall mean K score was 41.26±23.68,with a pass rate of 35.31%and honoring rate of 12.48%,respectively.The overall mean A score was 82.23±12.63,with pass rate of 96.57%and honoring rate of 69.37%,respectively.The overall mean P score was 73.03±15.06,with a pass rate of 85.64%and honoring rate of 39.86%,respectively.The correlation coefficient between K and A scores was 0.136(P<0.05).The correlation coefficient between K and P scores was 0.179(P<0.05).These results suggested positive correlations between K and A,and K and P scores.While the pass rate for K score in male staff was higher than that in female(P<0.05),there was no significant difference for A and P scores between the two groups(P >0.05).The K-A-P scores,and their associated pass rates and honoring rates among doctors were higher than that among nurses and medical technicians(P<0.05).Senior medical technicians had higher K and P scores than their junior counterparts(P<0.05).However,there was no significant difference in A scores among medical technicians with different ranks(P >0.05).Mean K-A-P scores and their associated pass rates and honoring rates in clinicians with higher degrees were superior,compared with those with lower degrees(P<0.05).Surgeons had higher K-A-P scores,pass rates,and honoring rates than others(P<0.05).Those who worked in teaching hospitals showed higher K-A-P scores,pass rates,and honoring rates than their counterparts in other work settings.There were no significant differences in K and P scores,and associated pass rates and good rates between medical staff from general hospitals and those from specialized oncology hospitals(P >0.05).However,higher P scores and associated pass rates were observed in staff from general hospitals than that from other settings(P<0.05).Over half(58.41%)of the medical staff spent less than 10%of their work time on nutritional education.About half(52.71%)of the medical staff expressed desires to work on nutritional research projects.Nutritional knowledge of medical staff primarily came from work experience(66.22%),reference textbooks and journals(65.40%),and formal education(61.25%).Conclusion While medical staff in China demonstrated positive attitude and good practice in nutritional therapy,they need more training to improve nutritional knowledge. | Xiao Wei Zhang Wei Li Gong Yan Chen Guang Fa Zhao Jian Si Chen Su Xia Luo TingYang Jin Huang Yan Jin Chen Su Yun Li Lan Zhou Wen Hu Chang Hai Zhao Shao Zhong Wei Han Ping Shi Chinese Society for Oncological Nutrition and Supportive Care(CSONSC) | 2017 | Journal of Nutritional Oncology2017，2，2： | 0 |
| 4 | Temperature difference-enhanced salinity gradient energy conversion enabled by thermostable hydrogel membrane with anti-swelling property显示文摘Coupling low-grade heat(LGH)with salinity gradient is an effective approach to increase the efficiency of the nanofluidic-membrane-based power generator.However,it is a challenge to fabricate membranes with high charge density that ensures ion permselectivity,while maintaining chemical and mechanical stability in this composite environment.Here,we develop a bis[2-(methacryloyloxy)ethyl]phosphate(BMAP)hydrogel membrane with good thermal stability and anti-swelling property through self-crosslinking of the selected monomer.By taking advantage of negative space charge and three-dimensional(3D)interconnected nanochannels,salinity gradient energy conversion efficiency is substantially enhanced by temperature difference.Theoretical and experimental results verify that LGH can largely weaken the concentration polarization,promoting transmembrane ion transport.As a result,such a hydrogel membrane delivers high-performance energy conversion with a power density of 11.53 W·m^(−2)under a negative temperature difference(NTD),showing a 193%increase compared with that without NTD. | Zhehua Zhang Teng Zhou Xiang-Yu Kong Yadong Wu Weiwen Xin Yanglansen Cui Linsen Yang Tingyang Li Xin Li Qingchen Wang Weipeng Chen Lei Jiang Liping Wen | 2023 | Nano Research2023，16，8： | 0 |
